实时时钟芯片DS1305用AVR90usb1287显示读秒的测试程序，对初学单片机的接触实时时钟的很有帮助(The test program for real-time clock DS1305 with AVR at90usb1287, very helpful for learner of AVR microcontroller )

which will use for MPC837XERDB when programming

说明：  c语言示例，学习C语言必备，很好的学习资料。(C language example, learning c language necessary, good learning materials.)

PIC单片机实现RS232-C串口通信，汇编语言(PIC microcontroller to realize RS232-C serial communication )

0.2通道180°相位差方波，3通道120°相位差方波，4通道90°相位差方波 1.试验平台stm32f103c8t6 2.2通道用定时器3的1、2通道；3通道用定时器3的1、2、3通道；4通道用定时器3的1、2、3、4通道； 3.实现方法，周期和占空比用捕获通道中断反复修改捕获值来实现 4.相位差采用定时器的生效同步规则来实现（下一次更新时间生效）(0.2 channel 180 degree phase difference square wave, 3 channel 120 degree phase difference square wave and 4 channel 90 degree phase difference square wave 1. Test platform stm32f103c8t6 2.2 channels use 1, 2 channels of timer 3; 3 channels use 1, 2, 3 channels of timer 3; 4 channels use 1, 2, 3, 4 channels of timer 3; 3. Realization method, period and duty cycle are realized by repeatedly modifying capture value with capture channel interrupt 4. The phase difference is realized by the effective synchronization rule of the timer (the next update time takes effect))

foxBMS 接口代码，德国的开源BMS开发共享平台，对于想了解BMS开发的比较有用(foxBMS code, from foxBMS in Germany, which is open source, and its useful for people who would like doing something about BMS)

Nuvoton NUC505使用LibMAD从USB、SD卡软解压播放mp3文件。需要我共享的LibMad库(Nuvoton NUC505 decode mp3 files by LibMAD USB/SD。Need my share LibMad.)
